More than one million Facebook users are pledging their support for U.S. presidential candidates or just urging Americans to vote, The Canadian Press reports.
About 1.4 million users of the social networking website -- including those in Canada -- are taking advantage of an election day feature to `donate' their status.
They can either declare their support for John McCain, Barack Obama, a write-in candidate or steer clear of partisanship and select `Just get out the vote!'
The selection then becomes the user's status update line, which is displayed to other Facebook friends.
Obama's campaign in particular, which collected US$640 million and shattered fundraising records, made heavy use of Internet and multimedia electioneering.
A 7.3. per cent rise in voter registration numbers suggests a large number of Americans are engaged in this election, and officials are bracing for a record voter turnout.
